Hello all,
Am trying to perform shape optimization task but i faced this error
would be glad if someone could help

This output is what happens when something has gone wrong with the command:
SU2_CFD config_CFD.cfg
within the subdirectories generated during optimization.



More information should be output to a log file inside the last subdirectory listed in the error output. If the error message there is not helpful, you can go to that directory and test the last command listed by the original error message.


You can also try running SU2_CFD with your original configuration file. That is the most likely place for there to be an issue.

The next most likely problem is that something changed by the optimizer in the config file causes the problem, which you'll be able to narrow down by comparing it against your original input file.
